Geometric Redesign of the Subdivided Surface of CC II: Application In Architecture
(Bucharest, Romania: SORGING–ROMANIAN SOCIETYFORENGINEERINGGRAPHICS, 2019)
The concave polyhedral surface of CC II can be used as a structural template for architectural design of domes, roofs or other covering or stand-alone structures. Subdivision of CC II faces in geometrically defined way can ...
Nonsingular acyclic matrices with full number of P-vertices
(Linear & Multilinear Algebra, 2013)
We classify the trees for which there is a nonsingular matrix where each vertex is a P-vertex. In particular, we show that such trees have an even number of vertices. Both results provide answers to questions proposed by ...
Note on right zero divisors in the ring of infinite upper triangular matrices over a field
(2017)
A bidiagonal matrix has only two non-zero diagonals. The matrix is called upper bidiagonal if these are the main diagonal and the principal subdiagonal. In this paper we will describe when infinite upper bidiagonal matrices ...
Estimation of thermal impulse response of a multi-layer building wall through in-situ experimental measurements in a dynamic regime with applications
(Elsevier Ltd, 2018)
The dynamic thermal characteristics of the components of a building have a primary influence on the energy performance of the building's envelope under real environmental conditions. In this study, a novel approach for ...
The clean graph of a commutative ring
(Charles Babbage Research Centre, 2017)
To gain a better understanding of clean rings and their relatives, the clean graph of a commutative ring with identity is introduced and its various properties established. Further investigation of clean graphs leads to ...
The line graph associated to the total graph of a commutative ring
(Ars Combinatoria, 2016)
Let R be a commutative ring with identity and T(Gamma(R)) its total graph. The subject of this article is the investigation of the properties of the corresponding line graph L(T(Gamma(R))). The classification of all ...
s-nil-čisti prsteni matrica
(VIII simpozijum "Matematika i primene", 11-2017, 2017)
Analiziraju se uslovi pod kojima se matrica nad prstenom može razložiti na zbir idempotentnih i jedne nilpotentne matrice.
Анализа прстена и модула придруживањем графова / The Analysis of the rings and modules using associated graphs
(Универзитет у Београду, Математички факултет, 2013)
Ova doktorska disertacija prouqava razliqite osobine komutativnihprstena i modula algebarsko kombinatornim metodama. Ako se graf naodgovarajui naqin pridrui prstenu R ili R-modulu M, onda ispitivaem egovih osobina dolazimo ...
Wireless sensor networks for civil structural monitoring / Primena bežičnih senzorskih mreža u monitoringu građevinskih konstrukcija
(Savez građevinskih inženjera Srbije, Beograd, 2010)
Development of communication technologies during last decade carried out possibility of application wireless sensor networks in many different areas. Recently frequently application of this technology in civil engineering ...
The maximum number of P-vertices of some nonsingular double star matrices
(Elsevier B.V., 2013)
In this short note, we construct a nonsingular matrix A whose graph is a double star of order n >= 4 with n - 2 P-vertices. This example leads to a positive answer, for n >= 6, to a last open question proposed recently by ...
